TALKING-MACHINE.

T 0 all whom it may concern:

Be it known that I, 'lnonas Kaamrna, a citizen of the United States,residing at Philadelphia, in the county of Philadelpl'iia and State ofPennsylvania, have invented certain new and useful Improvements inTalking-Machines, of which the following is a specification.

This invention relates to talkin machines and is directed to theprovision ot a machine of an improved construction in which the relativemovement of the sound-record and the reproducing mechanism necessary topermit. the stylus of the reproducing mechanism to track in therecord-groove throughoutthe several convolutions thereof is affected bymoving the sound-record and the turnt.ahle on-which it is supportedbodily in the plane in which they lie.

In accordance with my invention, a. turntable is. provided forsupporting a disk record and this is so mounted as to permit ofrectilinear movement thereof in the plane in .which itlies. A motormechanism is emploved for rotating the turntable on its axis an thismotor mechanism may also be arranged to cll'cct the lateral movement ofthe turntable. The reproducing mechanism is stationarily mounted withrespect to the turntable so far as concerns movement of that mechanismradially of the turntable;

if desired the reproducing mechanism may be so mounted as to permit ofmovement transverse to the plane of the turntable so that the stylusthcreol may track faithfully in the record-groove and may be moved to aninoperative position while changing records.

The devices whereby the motor mechanism, in addition to rotating theturntable, efi'ects the rectilinear movement thereof, are so constructedas to move the turntable bodilyas it is rotated at. the speed necessaryto enable the stylus of the reproducing mechanism to follow theret-m'd-groove properly. For this purpose the motor mechanism may bearranged to move with the turntable if desired, but I prefer to mountthe motor mechanism stationarily and connect it to the turntable bydevices which will permitof theneccssary relative movement of these twoparts while maintaining the PpBlut-lVC Specification of lettrs 'latent.

connection between them, as for instance, a. telescoping shaft or aspline.

The preferred embod1ment of my invention is illustrated in theaccompanying drawings in which- Figure l is a top view of a talkingmachine, broken away and sectioned in part, Fig. 2 is a. sectionalelevation of the same, the section being on line 22 of Fig. 1, and Figs.3 and 4 are detail views in section on lines 33 and 4-4 of Fig. 1.

Referring to these drawings, 1 indicates the motor-box of a talkingmachine having a frame 2 secured to the under side of the cover thereof.side of this frame are supports 3 in which the ends of 2 rods 4, 4: aresecured, these rods beingparallcl to each other and located adjacent toopposite edges of the frame 2. To the under side of frame 2 is secured amotor mechanism of any suitable construction, but preferably a.spring-motor 5 of the type commonly employed for driving the turntablesof talking machines. This motor mechanism drives a gear 6 which mesheswith a pinion T secured upon a shaft 8 which is mounted for rotation inbearings formed in standards 9 depending from the frameQ. One of thestandards .1 has a bearing formed therein for a rewinding shaft 10 bywhich the spring of the motor 5 is wound u the end of this shaft 10being adapted to ac engaged by a winding handle 11 of the usualconstruction. The shaft 8 has a. groove 12 cut therein and extendinglengthwise thereof.

A movable frame 13 has sleeves 14 of substantial length at opposite endsthereof through which the rods 4, 4t extend, and this frame carries therotatable turntable of the nun-thine. Referring to Fig. 3, it will beseen that frame 13 has two depending arms 15 integral therewith providedwith openings through which the shaft 8 extends, and a bevel-gear It;lies between these two arms 15 and 1s splined on shaft 8 by means of akey entering the groove 12. One of the arms to and the body portion offrame 13 have bearings formed therein fora vertitally-disposed shaft 17which extends 11 wardly through a slot lathe cover of t e motor-box 1and has the turntable 18 of the Vilma 21 shag and 31'' which I? iii-551aisms:

eeenee the two handles 51 end 52 together to the left, thereby slidingthe frame 13 along on the rods 4, ibeck to its initial position. Thenonreleesing the handles, the half-nut 47 will be drewn "into engagementwith the feed-screw 48 by spring 53, thereby moving the handle 51relatively to the handle 52 to the position shown in fig. 1 end theparts are in reediness for another reproduction. By turning the handle38 either at the conclusion of the first reproduction or after the partshave been brought beck to initial po' sition, the motor may be stoppedby the engement of the brake-pods with the colfifr end by adjustinghandle 38 between its extreme positions any speed of rotation of theturntable desired may be obtained.

Having now described m invention, whet I oleirn as new therein so desireto secure by Letters Patent is esfollows:

A talking-machine comprising a motorbox a. pair of rods secured to theunder side of the cover thereof, e frame slidable on said rods, :1 motorsecured to the under side of seid cover, two members splined togetherand roteteble on e horizontxil axis, one or said members being securedto the under side of said cover and driven by seid motor and the otherof seid members being mounted upon said frame, a. feed-screw mounted forrotation on the under side of seid cover, means ectueted by the motortor roteti the feed-screw, a shaft mounted on sai frame and rotatableabout a, verticel axis, intermeshin geers cerried by said shaft end saidmom r mounted upon the frame, a turn-table for e talking-machine recordmounted u on said shaft above the cover of the motor- K, s half-nutpivotelly mounted on seid slideble frame, on o ereting lever pivotnllymounted on said s iduble frame and arranged to move said half-nut intoand out of engagement with said feed-screw, and reproducing mechanismheld against lateral movement and adapted to coact with 3. record onseid turn-table, substantially as set forth.

This specification signed and witnessed this 28th day of July, 1908.
